Re: [Elecraft] Mcu ld
Paul, Refer to either the manual or K3 Utility "Force a Firmware Download" and follow the instructions given there. That condition is usually the result of a communications glitch during a firmware download. Always wait until the firmware load completes before touching the K3 or the computer. 73, Don W3FPR On 5/24/2020 6:10 AM, PAUL GM0BKC wrote: Hi all I have just tried to do the firmware update on my k3s, but come accross a problem and now it's stuck in MCU Ld And cannot get away from this now I have tried to follow the troobleshooting advice but still no joy.

Re: [Elecraft] MCU LD
Also try forcing an MCU load (from page 45 of the owner's manual): Forcing a Firmware Download If you accidentally load an old or incompatible firmware version and find the K3 unresponsive, do the following: (1) unplug the K3 from the power supply and wait 5 seconds; (2) plug the power supply back in; (3) hold the K3's POWER switch in; after about 10 seconds, you'll see the TX LED flash (you'll also see MCU LD on the LCD); (4) load the correct firmware version.

Re: [Elecraft] MCU LD
Hi Tom: After having built my K3 (s/n 2432) back in Jan, I agreed to build one for a good friend last month and ran into somewhat the same problems. The build went well, the unit received on the three bands from the XG2 at 1 microvolt and the K3 Utility would do the 5 and 50 watt TX Gain calibration as well as the filter set up in both the main Rx and the KRX3 sub receiver. The new K3 unit (s/n 3288) came with MCU Ver 3.14 and DSP Ver 2.16 installed and I decided to do an firmware upgrade to 3.19 / 2.17. The K3 Utility (Ver 1.2.8.10) is installed on a Dell D830 notebook and I'm using a native serial port directly to the K3 - this configuration has been used to do about 12 updates to my own K3 since I built it in Jan/09 all with no problems. When the K3 Utility was used to check the Firmware in the new K3, it confirmed the MCU, FPF and DSP1, but not DSP2. It acted as if the Aux DSP board for the KRX3 wasn't there. I tried to upload a full new Firmware vers set and it would load correctly the new MCU and FPF but would not load the new version of either DSP1 or DSP2. At the end of the load attempt the new MCU and FPF would remain but it would revert back to the original DSP1 Ver 2.16. I contacted K3Support and had prompt replies from both Dale and Gary and we tried various things. After checking and rechecking the connectors between the RF board and the Front Panel board, as well as the connectors between the DSP boards and the Front Panel board they asked me to measure the voltage at U1 pin 8 on the KIO3 board. It needs to be at least - 5 V DC. Mine was ok so then they sent me replacement Main and Aux DSP boards to try. Unfortunately the results were the same with the new Main DSP board. At this point Dale asked that I return the K3 to Aptos, which I did. It's there now and scheduled to be checked out Tues or Wed of this week. Good luck in getting yours fixed. I'll update you once I find out anything further with this one. 73, Doug VE3MV - Original Message - From: Georgens, Tom tom.georg...@netapp.com To: elecraft@mailman.qth.net Sent: Sunday, September 06, 2009 5:20 PM Subject: [Elecraft] MCU LD Hello - I am building a K3 kit and all was going well with the checkout and test when I decided to download the latest version of the firmware.

I get this all the time when I test the K3 Utility's ability to load a K3 in this state. Be very sure of the cable connection and COM port selection. Use the Windows Device Manager to verify the COM port if necessary. The K3 Utility should find the radio when you test communications from the ports tab. The expected speed is 38,400 and it should give you the warning dialog that says that the K3 Utility is waiting for MCU firmware. If you can't get that far, you can't load firmware.

Re: [Elecraft] MCU LD and K3 Utility
Running the utility trying to access an invalid port should not cause any problems at all, except that you won't be able to communicate with the K3. And invalid or missing port should not cause it to hang in any way. The first step is to load the Utility with *nothing* connected between the PC and K3. It should run normally except that it can't talk to the K3, so you won't get any report on current firmware, etc. You'll see ??? on the Utility screen in those places. You didn't describe your best efforts to uninstall and reinstall or what computer/OS you're using, but if you're running Windows that should include removing the program using the install/uninstall utility in the Control Panel, then rebooting the computer *before* trying to install the new Utility. Then, of course you download the utility program again from Elecraft rather than trying to install a potentially-corrupted version already on your HD. I may not have the latest K3 Utility, but the version I have and all the earlier ones offered a way to choose the port from the screens. Click on the PORT tab. If a list of ports isn't shown in the drop-down window, click REFRESH PORT LIST. Normally, if you're not sure which port works, you'd first be sure you have the K3 connected to the PC and turned on, then click on TEST COMMUNICATIONS. If that fails then you'd try a different port. In your case, the K3 is hung so it may not respond to a TEST COMMUNICATIONS query. In that case you need to force an MCU load as described on page of the Owner's Manual (Rev D). Since you don't know which port is correct, you may need to do that trying different ports until it works.

I tried to upload the latest firmware but as I was checking to see which serial port was connected to the computer, the K3 Utility blew up and in spite of my best efforts to uninstall and reinstall, when I launch it, it tried to connect to the K3 on a port that doesn't exist and just hangs and crashes. I've rebooted, looked for a .ini file that might be referenced for that bogus port, but I can't find it. Hi Pete, I was waiting to see if K6KR or someone more knowledgeable than I was around, but I guess not, so here goes. Run REGEDIT. Look for HKEY_CURRENT_USER\Software\Elecraft\K3 Utility That's where the port (and other) information is kept.

Re: [Elecraft] MCU LD and K3 Utility
Oops. Dick's and my e-mails crossed in cyberspace. He's the programmer and Utility expert. Like Vic I was responding only because no one else seemed to have been around (yet). My suggestions stand (and I apologize, I see now you did say you had Xp) but Dick is in the best position to lead through to the solution. 73 Ron AC7AC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
RE: [Elecraft] MCU LD
Don't attempt to load firmware into your K3 through a microHAM device. Use a USB to Serial Adapter or RS-232 cable that sends exactly what is sent by the K3 Utility. Some users have sometimes succeeded by changing the microHAM Router to a radio type none before loading K3 firmware, but sometimes (depending on the microHAM router version) that doesn't work either.

RE: [Elecraft] MCU LD
From the microKEYER Manual: If your radio includes upgradeable firmware, DO NOT perform any upgrade through microKEYER. That said, with any microHAM interface you must set the radio type to None (Ports | CAT | Set), check the Disable router queries box, check both Forward autoinformation to CAT port boxes, and set the 2nd CAT port to None before attempting an firmware update. After all of that you still need to keep a real serial port or a generic USB to RS-232 adapter for emergencies. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Sent: Tuesday, September 23, 2008 4:12 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] MCU LD OK, I tried to load new firmware to the K3, not using the USB-serial cable, but thru the micro keyer interface which is normally connected to the K3.

Re: [Elecraft] MCU LD
You need to set the radio selection in Router to none and I also turned off polling just in case. Do that and then upload the firmware again with the utility. - 73, Greg - AB7R Whidbey Island WA NA-065 On Tue Sep 23 13:12 , Eric sent: OK, I tried to load new firmware to the K3, not using the USB-serial cable, but thru the micro keyer interface which is normally connected to the K3.
